How do things persist? Are material objects spread out through time just as they are spread out through space? Or is temporal persistence quite different from spatial extension? This key question lies at the heart of any metaphysical exploration of the material world, and it plays a crucial part in debates about personal identity and survival. This book explores and compares three theories of persistence — endurance, perdurance, and stage theories — investigating the ways in which they attempt to account (...) for the world around us. Having provided valuable clarification of its two main rivals, the book concludes by advocating stage theory. Such a basic issue about the nature of the physical world naturally has close ties with other central philosophical problems. This book includes discussions of change and parthood, of how we refer to material objects at different times, of the doctrine of Humean supervenience, and of the modal features of material things. In particular, it contains new accounts of the nature of worldly vagueness, and of what binds material things together over time, distinguishing the career of a natural object from an arbitrary sequence of events. Each chapter concludes with a reflection about the impact of these metaphysical debates upon questions about our personal identity and survival. (shrink)

When people go shopping for gametes, their first and most important criterion is the donor's race. In so choosing, they are making wrong and invidious assumptions about what race is. They are also assuming that their child will develop her sense of self within those parameters. The effect is harmful both for children and for society at large. People should be able to recognize racial categories as they construct their own identities, but those categories should not limit their self‐identification from (...) the very outset. (shrink)

Review of Beauty and Revolution in Science, by JW McAllister.

Katherine Hawley explores and compares three theories of persistence -- endurance, perdurance, and stage theories - investigating the ways in which they attempt to account for the world around us. Having provided valuable clarification of its two main rivals, she concludes by advocating stage theory.

In _I Can Learn from You_, Michael Reichert and Richard Hawley—the authors of _Reaching Boys, Teaching Boys_—set out to probe deeply into the relational dynamics that help boys succeed as learners. Drawing on interviews with students and teachers in thirty-five schools across six countries, they examine the particular ways boys extend and receive empathy—modes of interaction that remain consistent across a wide range of schools, teachers, countries, and cultures. The book shows how teachers can help boys form productive learning (...) relationships and how schools can support the development of teachers’ relational capacities. At the heart of the book is the belief that educators must—and can—put relational teaching at the center of school life. (shrink)

I outline a number of parallels between trust and distrust, emphasising the significance of situations in which both trust and distrust would be an imposition upon the (dis)trustee. I develop an account of both trust and distrust in terms of commitment, and argue that this enables us to understand the nature of trustworthiness. Note that this article is available open access on the journal website.

Student-generated video creation assessments are an innovative and emerging form of assessment in higher education. Academic staff may be understandably reluctant to transform assessment practices without robust evidence of the benefits and rationale for doing so and some guidance regarding how to do so successfully. A systematic approach to searching the literature was conducted to identify relevant resources, which generated key documents, authors and internet sources which were thematically analysed. This comprehensive critical synthesis of literature is presented here under the (...) headings of findings from literature, relevance of digital capabilities, understanding the influence of local context and resources, and pedagogical considerations. Student-generated video creation for assessment is shown to have several benefits, notably in supporting development of digital and communication skills relevant to today’s world and in enhancing learning. As an emerging innovation within assessment, intentionally planning and supporting a change management process with both students and staff is required. The importance of alignment to learning outcomes, context and resources, choice of video format to desired skills development, and to relevance beyond graduation is emphasised for video creation in assessment to be used successfully. Video creation for assessment is likely to grow in popularity and it is hoped the evidence of benefits, rationale and guidance as to how to do this effectively presented here will support this transformation. Further research to consider video creation for assessment with individuals rather than collaborative group assessments, and to establish academic rigour and equivalence would be beneficial.

Katherine Hawley investigates what trustworthiness means in our lives. We become untrustworthy when we break promises, miss deadlines, or give unreliable information. But we can't be sure about what we can commit to. Hawley examines the social obstacles to trustworthiness, and explores how we can steer between overcommitment and undercommitment.

In this paper, I argue that there is a notion of 'counterfactual success' which stands to knowledge how as true belief stands to propositional knowledge. (I attempt to avoid the question of whether knowledge how is a type of propositional knowledge.).

Putative counterexamples to the Principle of Identity of Indiscernibles (PII) are notoriously inconclusive. I establish ground rules for debate in this area, offer a new response to such counterexamples for friends of the PII, but then argue that no response is entirely satisfactory. Finally, I undermine some positive arguments for PII.

What kind of entity is a committee, a book group or a band? I argue that committees and other such social groups are concrete, composite particulars, having ordinary human beings amongst their parts. So the committee members are literally parts of the committee. This mereological view of social groups was popular several decades ago, but fell out of favour following influential objections from David-Hillel Ruben. But recent years have seen a tidal wave of work in metaphysics, including the metaphysics of (...) parts and wholes. We now have the resources to rehabilitate the mereological view of social groups. I show how this can be done, and why we should bother. (shrink)

You can trust your friends. You should trust your friends. Not all of your friends all of the time: you can reasonably trust different friends to different degrees, and in different domains. Still, we often trust our friends, and it is often reasonable to do so. Why is this? In this paper I explore how and whether friendship gives us reasons to trust our friends, reasons which may outstrip or conflict with our epistemic reasons. In the final section, I will (...) sketch some related questions concerning trust based on the trustee’s race, gender, or other social identity. (shrink)

We articulate a view of natural kinds as complex universals. We do not attempt to argue for the existence of universals. Instead, we argue that, given the existence of universals, and of natural kinds, the latter can be understood in terms of the former, and that this provides a rich, flexible framework within which to discuss issues of indeterminacy, essentialism, induction, and reduction. Along the way, we develop a 'problem of the many' for universals.

Analytic metaphysics is in resurgence; there is renewed and vigorous interest in topics such as time, causation, persistence, parthood and possible worlds. We who share this interest often pay lip-service to the idea that metaphysics should be informed by modern science; some take this duty very seriously.2 But there is also a widespread suspicion that science cannot really contribute to metaphysics, and that scientific findings grossly underdetermine metaphysical claims. For some, this prompts the thought ‘so much the worse for metaphysics’; (...) others mutter ‘so much the worse for science’. (shrink)

In this chapter, I examine Lewis's ideas about ontological innocence, ontological commitment and double-counting, in his discussion of composition as identity in Parts of Classes. I attempt to understand these primarily as epistemic or methodological claims: how far can we get down this route without adopting radical metaphysical theses about composition as identity?

Much of what we learn from talking and listening does not qualify as testimonial knowledge: we can learn a great deal from other people without simply accepting what they say as being true. In this article, I examine the ways in which we acquire skills or knowledge how from our interactions with other people, and I discuss whether there is a useful notion of testimonial knowledge how.Keywords: Knowledge how; Practical knowledge; Tacit knowledge; Testimony; Skills; Assertion.

This article considers the extent to which health promotion strategies pose a threat to individual freedom. It begins by taking a look at health promotion strategies and at the historical development of health promotion in Britain. A theoretical context is then developed in which Berlin’s distinction between negative and positive liberty is used alongside the ideas of John Stuart Mill, Charles Taylor and T.H. Green to discuss the politics of health promotion and to identify the implications of conflicting perspectives on (...) freedom. The final section looks at current health promotion policy in Britain and beyond and argues that, if freedom is seen in terms of empowerment, health promotion can enhance individual freedom.

Katherine Hawley explores the key ideas about trust in this Very Short Introduction. Drawing on a wide range of disciplines including philosophy, psychology, and evolutionary biology, she emphasizes the nature and importance of trusting and being trusted, from our intimate bonds with significant others to our relationship with the state.

Material objects extend through space by having different spatial parts in different places. But how do they persist through time? According to some philosophers, things have temporal parts as well as spatial parts: accepting this is supposed to help us solve a whole bunch of metaphysical problems, and keep our philosophy in line with modern physics. Other philosophers disagree, arguing that neither metaphysics nor physics give us good reason to believe in temporal parts.

Vague existence can seem like the worst kind of vagueness in the world, or seem to be an entirely unintelligible notion. This bad reputation is based upon the rumour that if there is vague existence then there are non-existent objects. But the rumour is false: the modest brand of vague existence entailed by certain metaphysical theories of composition does not deserve its bad reputation.

People are described as suffering from impostor syndrome when they feel that their external markers of success are unwarranted, and fear being revealed as a fraud. Impostor syndrome is commonly framed as a troubling individual pathology, to be overcome through self-help strategies or therapy. But in many situations an individual’s impostor attitudes can be epistemically justified, even if they are factually mistaken: hostile social environments can create epistemic obstacles to self-knowledge. The concept of impostor syndrome prevalent in popular culture needs (...) greater critical scrutiny, as does its source, the concept of impostor phenomenon which features in psychological research.

If the property _being a methane molecule_ is a universal, then it is a structural universal: objects instantiate _being a methane molecule_ just in case they have the right sorts of proper parts arranged in the right sort of way. Lewis argued that there can be no satisfactory account of structural universals; in this paper I provide a satisfactory account.

The best arguments for the 1/3 answer to the Sleeping Beauty problem all require that when Beauty awakes on Monday she should be uncertain what day it is. I argue that this claim should be rejected, thereby clearing the way to accept the 1/2 solution.

If we are sympathetic to the project of naturalising metaphysics, how should we approach the metaphysics of the social world? What role can the social sciences play in metaphysical investigation? In the light of these questions, this paper examines three possible approaches to social metaphysics: inference to the best explanation from current social science, conceptual analysis, and Haslanger-inspired ameliorative projects.

I argue that, despite van Inwagen’s pessimism about the task, it is worth looking for answers to his General Composition Question. Such answers or ‘principles of composition’ tell us about the relationship between an object and its parts. I compare principles of composition with criteria of identity, arguing that, just as different sorts of thing satisfy different criteria of identity, they may satisfy different principles of composition. Variety in criteria of identity is not taken to reflect ontological variety in the (...) identity relation; I discuss whether variety in principles of composition should be taken to reflect ontological variety in the composition relation.

Philosophy of Science Today offers a state-of-the-art guide to this fast-developing area. An eminent international team of authors covers a wide range of topics at the intersection of philosophy and the sciences, including causation, realism, methodology, epistemology, and the philosophical foundations of physics, biology, and psychology.

Aaron Cotnoir does all sorts of interesting things in his contribution to this volume. He makes a helpful distinction between syntactic and semantic objections to the thesis that composition is identity, and outlines some empirical points relevant to the syntactic issue. But the centrepiece is his development of a formal framework for addressing the semantic objections.

The digital era has brought many opportunities - and many challenges - to teachers and students at all levels. Underlying questions about how technologies have changed the ways individuals read, write, and interact are questions about the ethics of participation in a digital world. As users consume and create seemingly infinite content, what are the moral guidelines that must be considered? How do we teach students to be responsible, ethical citizens in a digital world? This book shares practices across levels, (...) from teaching elementary students to adults, in an effort to explore these questions. It is organized into five sections that address the following aspects of teaching ethics in a digital world: ethical contexts, ethical selves, ethical communities, ethical stances, and ethical practices.
